# 2nd order differential equations solutions

Second-order case For $n=2$, by noting $y=x^m$, the ODE provides the indicial equation: \ [\boxed {am^2+ (b-a)m+c=0}\] with discriminant $\boxed {\Delta= (b-a)^2-4ac}$ and where the

## Second Order Differential Equations

In general, given a second order linear equation with the y-term missing y″ + p(t) y′ = g(t), we can solve it by the substitutions u = y′ and u′ = y″ to change the equation to a first order linear

To solve a linear second order differential equation of the form d2ydx2 + pdydx+ qy = 0 where p and qare constants, we must find the roots of the characteristic equation r2+ pr + q = 0 There are three cases, depending on the discriminant p2 - 4q. When it is positivewe get two real roots, and the solution is y = Aer1x + Ber2x zero See more
